A lady I work with has had a ferocious sinus infection and cough for 6 weeks. Lots of other co-workers and family members complaining of not feeling well for weeks on end. I also know of two individuals have gotten shingles which is unusual. Of course, I'd like to ask them if they had the jabs (which I believe they have), but I'm not bringing that up....many get defensive. Something has changed, especially with the Summer period being here where this sort of thing is not very common.
